Underwater lighting (was: Florida Flag Fish)
"... he had ordinary incandescent bulbs, hanging downwards from ceramic
sockets screwed to a board, partially submerged IN the water of each tank."
Has anyone considered (a safer version of) this as a possibility - using
something other than incandescent?
Presumably it would be a significantly more effective use of the light
output because there would be no partial reflection from the water surface &
the light source could be nearer to the plants.
Getting rid of the heat might be a problem though.
